Olfactory Advertising

In a ploy reminiscent to letting pies cool on windowsills, KFC is experimenting with aroma marketing, using scent to lure potential diners to their restaurants. The pilot program took place Aug. 23 at the Salvation Army offices in the Mayfair neighborhood.

Here's how it worked: plates of KFC's new "$2.99 Deals" were delivered by mail cart to employees, along with bills, packages and letters. The aroma of KFC chicken permeated throughout the office. Noses piqued, heads popped into the hallway, and the office workers were then treated to lunch.
